Excellent point George. Case in point, a Northern Thunderbird B100 crashed at CYVR and the two pilots died as a result of the crash, fortunately all the pax survived.
The initiating factor was an oil leak brought on by a loose filler cap. The plane was serviced the night before and the AME apprentice failed to properly secure it. His supervisor failed to see it and signed off as complete. The PIC who had over 10,000 hrs......did not do his pre-flight inspection!
The pax pointed out a pool of oil under the engine and this last chance to catch this 'little thing' was shrugged off by the pilot.
And unfortunately it 'bit them in the ass'
We all know what the acronym "ASSUME" means.
C-GXRX was one sweet looking King-Air!

Flying today I feel is alot cheaper respectively. We all enjoy the actual low cost of the flight (look at the ticket price compared to the miriad of taxes)
At these low prices, I just look at it like a form of public transit. You want to be pampered to? Charter a jet...I didn't think so!
And this form of public transit doesn't have crackheads shooting up in the aisles either!

Such a sad event. Two young pilots living their dream to fly having itt come to an abrubt end is tragic to say the least. I have always viewed those aircraft as one I wouldn't want to be in. I am sure they are just as safe as any other certfied twin turboprop.
I hope their families and co-workers can find comfort knowing the pilots have flown on from earthly existence to soar in the heavens above.
I patiently wait for the TSB to find out what transpired.

My brother who has just retired after 40yrs in the police services and has seen an abundance of technological advancement has a more sinister view, and I quote:
"It's VOODOO in there! " "Somewhere another chicken has just had its head chopped off!!"

They may have diverted if there was not a doctor on board to make that call.
Otherwise, I would think that they would probably have to treat it like they did, a medical emergency. If they didn't, they would probably open themselves to liability.
